Dendrobium marginatum. Batem. ms. 



This very pretty Dendrobium was obligingly sent to us, in 

 April of the present year, by Sigismund Rucker, Esq., from his 

 fine collection at West Hill, Wandsworth, with the name here 

 adopted. It would be easy to refer to nearly allied species of 

 this now extensive genus, especially to the Dendrobium hetero- 

 carpum, Wall, and Lindley, figured at our Tab. 4970, and its 

 several varieties there noticed, some of which are remarkable 

 enough, and this should perhaps rank as one of them. It is a 

 native of Moulmein, and was discovered by the Rev. C. S. P. 

 Parish and sent to Messrs. Hugh Low and Co. 



Descr. The stems, for they can scarcely be called pseudobulbs, 

 grow in clusters a foot and more long, are rather thicker than a 

 swan's quill, jointed (the joints slightly sheathing), angled ; the 

 younger ones bearing a few sparse linear-lanceolate /eaves towards 

 their extremity. Flowers, from the joints of the old stems, also 

 towards the upper part, generally in pairs, from one short pe- 

 duncle. Sepals and petals pure white, the former lanceolate, the 

 latter nearly ovate, much spreading. Lip moderately large, ta- 

 pering below into a long claw, as long as the spur, three-lobed ;
